Medical Terminology / Unit 1 MedTerm 0004 short lesson, about 20 seconds
The Prefix
Captions available
The idea
A prefix attaches to the front of a medical term and modifies it by position, number, time, or degree.
In practice
In the term pericarditis, the prefix peri means surrounding.
Where people slip
Prefixes are optional. Most medical terms have none, so a missing prefix is not a missing part.
